The chief forecaster's assessment adds: "Following a band of rain, sleet and snow, clearing southeastwards, rain, sleet and snow showers are likely to increasingly affect western parts of the UK.

"These will gradually fade overnight Tuesday into Wednesday, with icy stretches developing as skies clear, particularly where early snow has melted and then refrozen overnight. 0.5 to 3cm, locally 5cm of snow is likely at low levels."

Elsewhere the assessment said some places above 200m would see 7cm to 10cm."
